First EMV100 800 Series Manual page 79

LEGEND:
1. Selector switch for choosing the operation
2. Knob for setting temperature in DHWT (domestic hot water
tank)
3. Knob for setting temperature difference of heating source
(collectors, boiler, ...) and in user (hot water tank).
4. LED indicator for need for heating water in DHW tank. It
doesn't show working of el. heater.
5. LED indicator for pump operation.
Use of selector switch:
With selector switch (1) you select one of the following modes
of operation:
OFF Irrespective of temperature values the
pump and burner are off.
AUTO Automatic operation of thermostat
(normal operation)
ON 1 Irrespective of temperature values the pump is on. This
mode is designed for testing purposes, servicing and in case
of troubles.
ON 1+2 Irrespective of temperature values the pump and el.
heater are on. This mode is designed for testing purposes,
servicing and in case of troubles.
Mode OFF doesn't enable galvanic separation from
mains. When replacing the pump, disconnect supply
voltage!
TEMPERATURE SETTING OF HOT WATER TANK
With knob (2) you can set max. temperature
in water tank between 5°C and 85°C.
When the temperature is reached, thermostat
deactivates pump and closes motorised ball
valve regardless the temperature of heating
source.
If hot water is used by the appliance with
limited max. temperature of inflow, this setting is very useful.
DIFFERENCE SETTING
With knob (3) you can set temperature
difference of heating source (collectors,
boiler, ...) and in user (hot water tank)
between 0K and 15K.
Heating effect is provided, when heating
source temperature is higher than the
temperature of the user (water in hot water
tank). Consequently minimum difference
should be 3K-5K.
The difference is set in relation to the volume of heat losses of
the system which depend on lengths of pipes from source to the
3rd WAY OF USING
Cooling living space with blowing the cool outside air into
the living space
OPERATION
DTC 200/2G single differential thermostat measures the
temperature of outside air and inside air.
Cooling effect is provided, when cooling source temperature is
lower than the temperature of inside air. Consequently minimum
difference should be 2K.
When the temperature of outside air is below the temperature of
inside air it switches on the ventilator.
The thermostat switches off the ventilator if pre-set minimum
temperature is reached (adjustable from 5° to 85°C).

LEGEND:
1. Selector switch for choosing the operation
2. Knob for setting minimal ambient temperature
3. Knob for setting temperature difference of cooling source
(outside air) and ambient.
4. LED indicator - not in function
5. LED indicator for ventilator operation.
Use of selector switch:
With selector switch (1) you select one of the following modes
of operation:
OFF Irrespective of temperature
values the ventilator is off.
AUTO Automatic operation of
thermostat (normal operation)
ON 1 Irrespective of temperature values the
ventilator is on. This mode is designed for testing purposes,
servicing and in case of troubles.
ON 1+2 Irrespective of temperature values the ventilator is
on. This mode is designed for testing purposes, servicing and
in case of troubles.
Mode OFF doesn't enable galvanic separation from
mains. When replacing the pump, disconnect supply
voltage!
MINIMAL TEMPERATURE SETTING OF AMBIENT
With knob (2) you can set min. temperature in
ambient 5°C and 85°C.
When the ambient temperature is reached,
thermostat deactivates ventilator regardless the
temperature of cooling source (outside air).
DIFFERENCE SETTING
With knob (3) you can set temperature
difference of cooling source (outside air) and
in ambient between 0K and 15K.
Cooling effect is provided, when cooling source
temperature is lower than the temperature of
inside air. Consequently minimum difference
should be 2K.
